Resin 3D printing is known for its ability to produce highly detailed, high-resolution parts—but that precision can be easily lost if post-processing is rushed or done incorrectly. Cleaning your prints is more than just a rinse; it’s a critical step that directly impacts surface finish, mechanical performance, and long-term stability.
Here are the five most common cleaning mistakes in resin printing—and how to avoid them for professional-grade results every time.
1. Under-Curing or Over-Curing Before Cleaning
Some users clean prints immediately or cure them before removing residue—resulting in sticky or deformed parts.
The fix:
Let prints drip dry first. Then clean with IPA or water (depending on resin type), and only UV-cure after drying.
2. Leaving Prints in IPA (or Water) Too Long
Excessive soaking weakens prints, especially thin-walled ones.
The fix:
Stick to a 2–5 min IPA or 3–10 min water wash. Use a timer or wash-and-cure station for consistency.
3. Using Dirty Cleaning Liquids
Contaminated IPA or water can redeposit uncured resin, leading to tacky prints.
The fix:
Filter and refresh liquids regularly. Use a two-stage rinse system if needed.
4. Aggressive Scrubbing or Handling
Stiff brushes or rough handling can snap small features or scratch surfaces.
The fix:
Use soft tools and gentle swirling. Handle prints with gloves and care.
5. Skipping the Final Drying Step
Residual liquid on parts before curing causes hazy or bubbled finishes.
The fix:
Air dry or use compressed air before curing to ensure a clean, even surface.
Pro Tips for Consistently Clean Prints

Use a wash and cure station
-
Keep wash tools separate and clean
-
Cure rinse water or IPA before disposal
-
Always filter resin before and after use
